If you're feeling good about the market, you're not alone. Take my hand as we go over some of this week's more uplifting headlines.

1. Tesla's new parking space
Tesla Motors (TSLA 12.06%) has had an amazing run. The electric car maker has seen its shares nearly triple over the past three months, and the big move up is paying off.

There's a vacancy on the Nasdaq 100 index that tracks the 100 largest non-financial securities on the exchange, and come next week, it will be Tesla Motors that takes the slot. Naturally, the fast-growing automaker wouldn't have made the cut if its well-received growth initiatives and surprising quarterly profit hadn't helped make the stock one of the market's biggest winners in 2013.

Nasdaq 100 isn't as widely duplicated by index fund managers as the S&P 500, but it should still be good for some additional buying activity.

2. Sirius growth
Shares of Sirius XM Radio (SIRI) hit a five-year high after announcing that it has surpassed 25 million subscribers for its satellite radio service.

Sirius XM closed out the second quarter with 715,000 more subscribers than it had when the period began, and that three-month spurt is impressive considering that the media darling was only targeting 1.4 million net new accounts for the entire year.

Sirius XM is boosting its guidance on that front slightly higher -- to 1.5 million -- but even that new goal appears to be conservative. It's just as well. Sirius XM boosted its subscriber target four times last year.

3. Nu attitude
With the economy showing signs of life, we're starting to see some companies inch their outlooks higher, but sometimes, an upward revision is a real eye opener.

Nu Skin Enterprises (NUS -2.20%) was a big winner on Wednesday after juicing up its growth goals. The skin-care and nutritional products maker now sees a profit of roughly $1.20 a share on $680 million in revenue, well ahead of its prior guidance, now calling for more than $0.95 a share, and $580 million in revenue.

This isn't just a quarterly spike. Nu Skin is raising its revenue guidance for all of 2013 by $320 million, suggesting that the second half of the year will also be treated to quarterly revenue clocking in at an average of slightly more than the second quarter's $100 million top-line beat.

4. Facebook tosses out a wider net
Facebook (META -0.52%) rolled out Graph Search -- its potentially bar-raising social search platform -- in January, on a beta basis.

This week, it began rolling it out to everyone.

Graph Search allows users to search friends, and friends of friends, for information. There are plenty of sites out there where you can get a review for an Aspen ski resort or dentist referrals, but there's something tantalizing about knowing that a friend (or a friend of a friend) has been to the same ski lodge, or happens to be a dentist.

Just wait until that next job interview comes around. It will be awfully tempting to hit up Graph Search to see if you have any friends who have friends already working at the company.

This is obviously not the best time to be rolling out a personalized search option. We're all growing suspicious of the information that's readily available online about ourselves. However, Facebook's Graph Search has a good shot at being a game changer.

If you don't see it that way, maybe you can use Graph Search to find fellow Facebook bears.

5. Streaming is the new optical disc
It seems as if a week doesn't go by without Netflix (NFLX -3.92%) beefing up its digital vault.

This week kicked off with Netflix extending its multiyear licensing deal with CBS, adding more of the major network's shows, including L.A. Complex and CSI: NY.

On Thursday, Netflix's latest stab at original first-run programming became available. Orange is the New Black -- a gritty yet occasionally lighthearted series from Weeds creator Jenji Kohan about a women's prison -- made every episode of the first season available. Reviews have been generally positive, and Netflix has already ordered up a second season.

Steady original programming is one way to keep subscribers incarcerated to the service itself.
